Mobile radioactive liquid waste treatment equipment

Abstract

The invention discloses a movable treatment device for radioactive waste water, which comprises a protecting vehicle, a heat preservation cabin, a treatment system of waste water, a PLC controlling system and an external connecting pipeline, wherein, the treatment system of waste waster consists of a liquid and solid separator, a pre-filter, an ultra-filter, a security filter, a reverse osmosis filter of two levels and a combined adsorption device; the PLC system consists of a PLC, a flow meter, a conductivity meter, a radioactivity detector and a pressure controlling device. The invention solves the contradiction between the low interception and adsorption efficiency of nuclide and small size under the condition of large flow, meanwhile, which solves the problems of integration of a plurality of techniques and protection of the movable treatment device of radioactive waste water and realizes automatic operation, safety and reliability in the overall process.

Description

Technical field: [0001] The invention belongs to a radioactive waste water treatment device, in particular to a mobile radioactive waste water treatment equipment. Background technique: [0002] In recent years, nuclear power plants, nuclear device leakage accidents and terrorist attacks of the spread of radioactive pollution have occurred frequently, resulting in increasingly prominent public environment and public safety issues, especially in large and medium-sized cities with concentrated populations. Mobile radioactive wastewater treatment equipment is required for The radioactive waste water produced in response to nuclear pollution emergencies should be disposed of. [0003] In large and medium-sized cities, the cleaning water for radioactive wastewater treatment is generally municipal tap water, and the salt content of the treated wastewater should also be less than 1000mg / L. After solid-liquid separation and flocculation treatment, tank storage is adopted in accordan...

AI Technical Summary

Problems solved by technology

[0004] The radioactive wastewater treatment equipment in the prior art basically adopts the ground treatment device, which adopts the technology of nanofiltration and anion-cation exchanger, which is difficult to achieve miniaturization and light weight, and is not suitable for making mobile equipment

At the same time, the desalination rate of the nanofiltration membrane is low, and the performance of intercepting ionic radionuclides is quite different from that of the reverse osmosis membrane with a high desalination rate.

In addition, the radioactive wastewater treatment system in the prior art lacks the necessary detection equipment, and cannot perform quantitative treatment and automatic control
